The Zwiftcasters welcome 2018 with lots of chat about the Zwift getting bigger – in both senses. The roads are longer, with the London expansion, and the roads are busier, are thousands of new Zwifters flooding on to the platform.

Simon, Shane and Nathan try to make sense of it all – and look at the statistics, combining insight, public information and naked guesswork to try to assess the scale of the Zwift universe.

Meanwhile the chaps discuss the Surrey Hills expansion. It may not be as visually spectacular as recent developments, but there could be some very interesting business reasons behind the new roads.

The consequences of growth is a continuing theme as Simon sits down for a chat with Zwift’s VP of Events, Charlie Issendorf. Amongst other things, Charlie reveals that the Zwift HQ is seriously considering limiting entry to some events – Shane sniffs a clever marketing ruse. Charlie also reveals that a “club portal” is soon to launch, giving benefits like private rides and club kit to qualifying groups.

Simon puts three of the best trainers, the Neo, Drivo and Kickr into the Zwiftcast sound lab to get a rounded picture of just how loud or quiet are the competing top offerings from Tacx, Elite and Wahoo.

ZwiftQuest could be a whole new way of Zwifting – it’s competitive but it’s not a conventional race. Simon talks to ZwiftQuest pioneer Jonny Noblett.
